Abstract: Techniques for radar detection based on preacquisition ramps are discussed. One example system comprises transmitter circuitry, receiver circuitry, and one or more processors. The transmitter circuitry can transmit preacquisition ramps and acquisition ramps. The receiver circuitry can receive preacquisition signals and acquisition signals based on interactions between the environment and the preacquisition ramps and acquisition ramps, respectively. The one or more processors can perform preprocessing based on the preacquisition signals to obtain interim results based on one or more of the environment or the system; generate a range Doppler map based at least in part on the acquisition signals; and evaluate the range Doppler map based at least in part on the interim results.

Abstract: A device is suggested for processing input data received by several antennas, the device including a processing unit including a buffer and at least one multiplier, wherein the processing unit is configured to calculate a second stage FFT result based on input data received by a first antenna, multiply the second stage FFT result for the first antenna with a first compensation value, and store the result in the buffer. The processing unit is further configured to calculate a second stage FFT result based on input data received by a second antenna, multiply the second stage FFT for the second antenna with a second compensation value, and add the result to the value stored in the buffer.
